Research gathered on synthetic drug markets trails behind studies on other illegal drug markets. Synthetic drug's relatively recent classification as an illicit substance, coupled with its distinct characteristics that insulate it from detection has hindered the development of reliable assessments of the markets structural features. The purpose of this study is to provide reliable insight into the inner dynamics of Quebec’s synthetic drug industry, focusing on its organizational features. Using information derived from 365 synthetic drugs seized by law enforcement over a one year period, this study will merge two techniques, drug composition and economic analyses, under a common framework to derive reliable and comprehensive assessments of the structure of Quebec's synthetic drug market. Drug composition analysis examines the drug’s chemical and physical profile to make inferences about the market structure while the economic analysis examines price determinants for the same market, providing further insight into its dynamics and distinctive features. Findings from the drug composition analysis indicate that the synthetic drug market in Quebec is likely to be composed of a high number of small structures, indicating a competitive market. The economic analysis provided complementary information, finding that both differential production costs and trafficker-consumer relations may influence price variations, depending on the region. This study concludes by emphasizing that drug composition analysis should be diligently pursued by both researchers and enforcement organizations alike to effectively target and enhance our understanding of the intricate processes that underlie the synthetic drug market.
